I've been using it for a long time as well, but I'm really tired of the constant up-sell attempts. I really just want a dead simple app to track my work, and I really feel like Jefit is moving further and further away from that.
If you're on iOS, consider this completely crazy idea:
Apple Numbers.
I started doing this with Excel, but the AN experience on mobile is great. You can even add simple forms.
Heavyset on iOS should fit the bill perfectly. It has everything I want in a workout tracker (weights based on percentage of training max, workout calculator, Apple Health integration) and nothing more. https://www.runloop.com/heavyset
If you’re on iOS, the app “Strong” is a really simple but great tracking app. On Android there is “FitNotes” which is a little bit more barebones, but still really functional. I have tried Jefit a few times and think it’s great but ended up using these other ones because of their simplicity.
